Jon Robson 614da1dc5e Features: Make max width a feature
Making this a feature part of the feature management system is integral
to making this a toggle and will allow us to explore making this
persistent in future.

Jon Robson 6b7bc78bae Update name of body class to avoid confusion
The class vector-feature-table-of-contents-disabled is confusing as
it shows on pages with table of contents. What it actually means
is the A/B test is disabled. This change gives it a more meaningful name.

Use the class name vector-feature-table-of-contents-legacy-toc-enabled
to describe it better.

Jon Robson 9689974d0d AB test: Complain when TOC experiment setup incorrectly
Throw a runtime exception if the TOC experiment is setup correctly.
Otherwise this leads to confusion.

There must be 3 buckets, with 0 unsampled and equally weighted

Clare Ming eb597645c3 Refactor TOC A/B test to bucket users on backend
- Include temporary feature requirement for TOC A/B test.
  - Assumes 100% of logged-in users with even/odd user ids
  being assigned to treatment/control buckets respectively.
  - Sampling rates passed in by config are not considered
  during bucketing.
- Update hook for adding needed TOC A/B test body classes.
- Add test for temp feature.

Note: the temporary feature requirement and associated hooks
should be removed once the 2nd TOC A/B test concludes.

Jon Robson d74890df63 [Grid preparation] Add feature flag for grid
Additional changes:
* Make the query string parameter optional and if not defined set it
to lowercase configuration name. I think this makes it more predictable
as some configuration flags are prefixed with vector and some without.

This has the following consequences:
languageinheader => vectorlanguageinheader
languageinmainpageheader => vectorlanguageinmainpageheader
languagealertinsidebar => vectorlanguagealertinsidebar
titleabovetabs => vectortitleabovetabs

Note since table of contents query string is used in the A/B test
I've kept that as tableofcontents for now.

Jon Robson eca9fcbf79 Drop the LatestSkinVersionRequirement
The LatestSkinVersionRequirement is problematic for various reasons:

1) It uses the "useskin" query string
parameter which may or may not refer to the correct
skin (in the case of a non-existent skin it will always come to the conclusion that
it is not modern Vector and thus must be legacy).

2) It uses the User object which may or may not be safeToLoad
depending on when called.

The feature seems redundant at this point, as we are separating code
into separate classes Vector and Vector22 and all the features only apply
to modern Vector. I suggest we remove it and use the features explicitly in the skin
intended.

jdlrobson d8382ec96b Drop search related feature flags
Given Wikidata is the only project using modern Vector,
and the only project where the search API is not applicable,
this will result in a loss of autocomplete on Wikidata.org
which will fall back to the non-JS mode.

jdlrobson ef59d7b973 Disable table of contents in article body
This will currently remove table of contents in article body
for legacy and modern skin.

To prevent us deploying this in current form, a check is
added in generateHTML

This requires an adjustment of OverridableConfigRequirement to
support requirements which do not vary on whether the user is
logged in or not.

Nicholas Ray de5a640c0b Allow languageinheader query param to fully control treatment of languages
Before this commit the `languageinheader` query param would only take
effect if the A/B test was enabled AND the query param was set. Per
T282543, we want the query param to take effect regardless of the state
of the language/AB test config.

To see new treatment, set `languageinheader=1`.
To see old treatment, set `languageinheader=0`.

Nicholas Ray 49f2b25737 Create A/B test harness for Language in header feature
* Adds ab test config to enable/disable the ab test. Defaults to `false`
(ab test disabled).

* Adds a `languageinheader` query param which only takes effect when the
ab test is enabled. The query param is cast to a bool and determines
which treatment is shown. For example, set query param to
`languageinheader=1` to see the new treatment. Set query param to
`languageinheader=0` to see the old treatment. To bucket based on the
user's id or global user's id, don't set the query param.

* Moves the language in header config work that was previously in
ServiceWiring into a `LanguageInHeaderTreatmentRequirement` class so
that unit tests can be done on most of the logic that determines whether
the language in header will show.

* Adds logic to bucket user based on [global] user id.

In preparation for the new A/B test requirement, a custom requirement

support OR operations and the desired effect is the case where:

* the SearchInHeader feature flag has been enabled
* OR the SearchInHeaderABTest feature flag has been enabled and the user is bucketed

jenkins-bot ec6307e669 Merge "[fix] "Existing account only" skin version config" 2020-04-29 18:55:30 +00:00
Stephen Niedzielski 709772fa12 [fix] "Existing account only" skin version config
de76ab5 added the config,
`$wgVectorDefaultSkinVersionForExistingAccounts`. Its usage in
`Hooks::onUserGetDefaultOptions()` was invoked not only for existing
accounts but anonymous users _as well._  This is a bug, due to my own
misconceptions about the hook, that went against both the config's name
and its documentation.

Unfortunately, user sessions are unavailable in
`Hooks::onUserGetDefaultOptions()` so it does not seem to be possible to
determine whether the active user is an anonymous or existing account.
This patch drops the hook and centralizes all version determination
logic in SkinVersionLookup::getVersion(). SkinVersionLookup requires a
the active User object and can make the anonymous / existing account
determination by checking login state.

The issued was identified while responding to review feedback given by
@polishdeveloper / @pmiazga in
I52d80942b4270c008d4e45050589ed9220255a50.

Changes:

- Add the LatestSkinVersionRequirement requirement class, which lazily
  evaluates the application state to get the version of the skin for the
  request.

  This majority of this class is taken from Stephen Niedzielski's
  Vector\SkinVersionLookup class, which was introduced in d1072d0fdf.

- Register an instance of LatestSkinVersionRequirement and register the
  'LatestSkin' feature that requires that requirement

- Re-introduce SkinVector::isLegacy and make it defer to the Feature
  Manager

Sam Smith 84226b41b6 featureManager: Add DynamicConfigRequirement requirement
We expect the vast majority of requirements and features to be defined
in services as possible. However, there are some "complex" requirements
that require additional application/HTTP request state. Unfortunately,
service wiring is done before some of that state is available.

I65702426 attempted to work around this by requiring clients of the
Feature Manager to pass that additional state on every interaction with
the system. Those complex requirements would then select the parts of
the state that they required when it was required. However
implementations of \IContextSource are God objects and their use should
be limited.

Whilst reviewing I65702426, Stephen Niedzielski mentioned that the
application state being available is a requirement. This remarkably
simple solution:

- Keeps the Requirement interface and FeatureManager API free of God
  objects;

- Is true to the nature of the Feature Manager - it makes clear and
  centralizes the various checks for application state being available
  across the codebase; and

- Inject a Requirement implementations' dependencies at construction
  time

It just so happens that the $wgFullyInitialised variable flags whether
the application state is available...

Changes:

- Add the the FeatureManager\Requirements\DynamicConfigRequirement class
  and tests. The DynamicConfigRequirement lazily evaluates a single
  configuration value whenever ::isMet is invoked

- Register an DynamicConfigRequirement instance, configured to evaluate
  $wgFullyInitialised while constructing the Vector.FeatureManager
  service

Sam Smith d14caf2f11 featureManager: Add Requirement interface
FeatureManager::registerRequirement established the interface for a
requirement: its name and whether it's met.

However, the Feature Manager also needs to handle scenarios where a
requirement needs additional context before it can be considered met.
That context may not be available when the application is booting, e.g.
checking if the user is logged in; or the logic is complicated enough
that it should be under test.

Changes:

- Add the Requirement interface and update FeatureManager to work with
  implementations of it

- Maintain B/C by constructing an instance of a the SimpleRequirement
  DTO

As was noted in https://phabricator.wikimedia.org/T244481#5859513, the
term "set" doesn't seem natural. Piotr Miazga (polishdeveloper, pmiazga)

including "requirement." Serendipitously, this term is already used in
FeatureManager's documentation.

Sam Smith 9177c22365 features: Add minimalist feature manager
With complex additions to Vector's codebase like the Desktop Improvement
Program upcoming, it's important that we have a shared, intuitive
language to talk about features and their requirements. Centralising
the registration of features and creating an API satisfies does exactly
this.

This change introduces a greatly-reduced version of Piotr Miazga's
(polishdeveloper, pmiazga) original proposed API and associated
scaffolding classes for feature management in Vector, which itself was
based upon his work in MobileFrontend/MinervaNeue. This is done to
establish a foundation upon which we can build the more sophisticated
parts of Piotr's proposal in a piecemeal basis, thereby minimising risk.

Distinct from Piotr's proposed API is the ability to register sets and
features that are always enabled or disabled.

Additionally:

- A Vector.FeatureManager service is registered but not used

- A list of proposed immediate next steps is included
